Market context

Shenzhen will experience early-summer conditions on 8 June 2026, with the highest daily temperature recorded at Bao'an International Airport Station determining the settlement outcome. June typically marks the onset of Shenzhen's pre-monsoon season, when daytime highs range between 28 and 34 degrees Celsius, though occasional heat waves can push readings several degrees higher. The specific resolution source—Wunderground's historical data feed for the airport station—provides a standardised, publicly accessible reference point that eliminates ambiguity around measurement location or methodology.

Historical June temperature records for Shenzhen show considerable year-to-year variation. The airport station has recorded June highs as low as 26 degrees and as high as 37 degrees over recent decades, reflecting both typical subtropical patterns and occasional anomalous heat events. Current crowd probability of 0% suggests traders are pricing in either a narrow expected range or significant uncertainty about which temperature bracket will materialise. Comparable June settlements at this location have typically clustered in the 30–34 degree band, though outlier outcomes remain plausible given Shenzhen's exposure to tropical air masses and occasional early-season typhoon activity.

Traders should monitor China Meteorological Administration forecasts released in early June, which typically provide 7–10 day outlooks with reasonable accuracy for maximum temperatures. Any tropical cyclone activity in the South China Sea during late May or early June could materially shift conditions. The settlement window closes at 12:00 UTC on 8 June, allowing only same-day resolution once final readings are confirmed on Wunderground, which typically updates historical data within 24 hours of observation.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
